FAQ
FAQ
Q1: What is the main function of the 1734-IE4C?
It is a POINT I/O analog input module used to read up to four current loop signals (0–20 mA or 4–20 mA) into a PLC system.
Q2: What type of signals does it support?
It supports standard industrial current signals, mainly 4–20 mA and 0–20 mA transmitters.
Q3: How many input channels does it have?
The module provides four single-ended analog input channels.
Q4: Does it provide channel isolation?
No, the channels are non-isolated, so all inputs share a common reference.
Q5: What resolution does the module use?
It uses a 16-bit resolution over a 0–21 mA measurement range for high precision.
Q6: What terminal bases are compatible?
It works with POINT I/O bases such as 1734-TB, 1734-TB3, and 1734-TB3S.
Q7: What is the typical update time?
Depending on configuration and filtering, update time is typically around 200–240 ms.
Q8: Where is this module commonly used?
It is widely used in process automation systems such as temperature monitoring, pressure measurement, flow control, and industrial instrumentation loops.
